I personally just want to do as many different things as I can do, whether it's comedy, drama, science fiction, horror, narrator... You've got a documentary, I've got a voice. Animated films. Big films, small films.

Anything that's different from your own realm of experience as a human being, whether it's driving a car or a boat, or using guns, anything that separates you from yourself and leads you more towards this character's existence is a big help.

I love working with horses. People say you shouldn't work with animals and children; that's wrong. You must only work with children, because you only work eight hours a day and I love working with animals. Animals have an honesty that human beings reach to find in their lives at the best of times.

I hadn't really met Colin [Farell]. It's really weird to say: 'Oh, hello, I'm Kate...I'm Colin.. shall we?' That's a bit strange. Len was fine with it. We've gone through this experience with Scott Speedman before on the first Underworld move. It was our little version of swinging. We survived that.

I did loads of auditions and I didn't get called back. I still get giddy at all the people I get to work with, and I'm still enjoying the work and enjoying life too much that I don't feel like I've done that much.

But we're born as children and we look at the world with open eyes... And we don't judge and we don't betray. We're not jealous. We're not envious. We're not even weary, which is a danger also as kids. They have to learn a certain amount of awareness.

I love the grandiosity, how sweepingly entertaining films can be. And I think there's a place for films that pry more into the human condition.
